6Claims.

This invention relates to improvements in containers.

The objects of this invention are:

First, to provide a container formed mainlyof fibrous material which issuitable for use in the dispensing of oils and greases.

Second, to provide a leak-proof container formed mainly of fibrousmaterial in which the imperfections of material, such as "pin-holes"common in paper and materials formed of fiber and resulting frommanufacturing conditions, seemingly impossible to eradicate, arerendered unimportant.

Third, to provide a container adapted for the uses stated and having theadvantages stated which may be produced economically and on a largescale.

Objects pertaining to details and economies of the invention willdefinitely appear from the description to follow. The invention isdefined in the claims.

A structure which embodies the features of our invention is clearlyillustrated in the accompanying drawing in which:

Fig. 1 is a perspective view of a sealed container embodying thefeatures of our invention.

Fig. 2 is a fragmentary longitudinal section.

Fig. 3 is an enlarged detail section on line 3-3 of Fig. 1.

Fig. 4 is an enlarged detail section on a line corresponding to line 4 4of Fig. 1.

Fig. 5 is an enlarged detail section taken on a line corresponding toline 5-5 of Fig. 1.

Fig. 6 is an inverted view.

Our container is especially designed for use in dispensing oils such aslubricating oils and greases such as lubricating greases, lard and thelike. It is now quite common practice to dispense lubricating oils fromoriginal containers as a means of insuring to the customer that he isreceiving the kind and quality of lubricant desired. The containers aredestroyed or rendered useless in the dispensing so it is highlydesirable to provide a container which may be economically produced andat the same time is effective in retaining oils and greases whichpenetrate the ordinary fibrous containers.

In the accompanying drawing we have illustrated an embodiment of ourinvention as adapted for the dispensing of lubricant. Our containercomprises a tubular side wall I of fibrous material preferably formed ona spiral wind tube forming machine. The details of the wall structureare not illustrated as spiral wind tube forming machines are well knownin the art. The side wall, however, should be continuous from end toend.

We provide a lining consisting of superimposed layers 2 and 3 ofgrease-proof paper, these being adhesively secured together throughoutby an adhesive conventionally indicated at 4. The multi-ply lining isadhesively secured throughout by a layer of glue indicated at 5. We havefound that certain dextrin glues are satisfactory for this purpose.

The lining is preferably formed by spirally winding the lining layerstogether with their joints overlapping as indicated at 6, Fig. 4. Thelining may be applied as the side wall is formed in the event the sidewall is formed on a tube machine. The lining is continuous from end toend of the side wall and by forming it of multiply paper any pin-holesor slight, fractures which commonly'occur in the manufacture of paperare sealed, and the likelihood of the pin-holes or slight fracturesregistering is extremely remote. Should such a thing occur the doublelayer of adhesive seals the same.

In the embodiment illustrated the container is provided with a tin cover1 having a peripheral flange 8 seamed and clamped over the upper edge ofthe container side wall, this being commonly? applied by machinery, andthe reverseiy turned outer portion 9 of the cover is clamped upon thewall with its edge i0 slightly embedded therein. This retains the coverfor handling and also provides an effective seal, the flange of thecoverbeing in compressing sealing engagement with the wall.

The other end of the container is closed by an inner end member ll offibrous material having a downturned flange i2 telescoped within theside wall member. This inner end member is provided with a liningconsisting of superimposed layers i3 and ll of grease-proof materialadhesively secured together throughout as indicated at |5 and secured tothe lining as indicated at i6. These inner end member linings extendover the flange i2 and they are adhesively secured to the wall lining atH. The end i8 of the side wall member is folded inwardly upon the innerside of the flange I2 and adhesively secured thereto at i9. The outerdisk-like end member 20 is forced into this inturned portion l8 of theside wall member so that its edges are in clamping engagement therewithas indicated at 2| with the outer end member in supporting engagementwith the inner end member. The outer end member is preferably of stockcorresponding to that of the side walls and as indicated may, withadvantage, be slightly thicker than the side wall stock.

With this arrangement of parts the joint between the side walls and theend members is effectively sealed so that liquid or oil cannot escapetherethrough. One of the advantages of our invention is that thearrangement of parts permits production of the container at high speedor in large quantities with uniform results and with little likelihoodof the containers leaking or permitting the escape of oils or greases.

In the embodiment illustrated, in which the top of the container isformed of tin, so that it may be pierced by the dispensing spout nowquite commonly used in the dispensing of lubricant by service stations,we preferably provide the outer end member with a vent break-out portion22 which is partially severed by an annular series of slits orperforations 23 so that, after the dispensing spout has been inserted inthe turn cover.

I and the container inverted or in discharging position, the knock-outvent can be easily knocked out or broken to permit the free entranceofair. This also has the advantage of preventing re-use of the container,which is one desired feature in the dispending of fluids, lubricants forexample.

We have illustrated and described our invention in an embodiment whichwe have found very satisfactory. We have not attempted to show variousadaptations and modifications in structural detail which we contemplateas we believe this disclosure will enable those skilled in the art toembody or'adapt our invention as may be desired.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is:
